Pku and albinism are two autosomal recessive disorders, unlinked in human beings. if couple each of them heterozygous for both traits, produce a child, what is the chance of their having a child with (a)pku (b)albinism (c)both traits?

a) 3/16; b) 3/16; c) 1/16

Explanation:

PKU and albinism are two autosomal recessive disorders. The possible genotypes and phenotypes for each disease are:

PKU

Albinism

If a couple of individuals heterozygous for both genes (PpAa) has offspring, from the Punnett Square we get the chances of them having:

ppA_: 3/16

P_aa: 3/16

ppaa: 1/16

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
